It includes: * An advanced C++ code editor * Integrated GUI layout and forms designer * Project and build management tools * Integrated, context-sensitive help system * Visual debugger * Rapid code navigation tools * Supports multiple platforms * Qt Quick Designer ``` Qt Creator has a code model which shows errors as the project is being worked on. However, in the event that clang-8's include files are missing (which was the case because I did not have clang-8 installed, just libclang1-8 which was the actual dependency, and clang-10), the Clang code model shows errors about "stddef" not being found, thus indirectly causing C++ Qt projects to show a lot of phantom errors. This is essentially a missing-dependency issue; Qt Creator expects the include files of the Clang version it was compiled with, and it doesn't get them. The exact issue was determined via: ``` ldd /usr/lib/x86_64-linux-gnu/qtcreator/libexec/clangbackend linux-vdso.so.1 (0x00007ffde3bee000) libSqlite.so.4 => /usr/lib/x86_64-linux-gnu/qtcreator/libexec/../libSqlite.so.4 (0x00007fe611caf000) libClangsupport.so.4 => /usr/lib/x86_64-linux-gnu/qtcreator/libexec/../libClangsupport.so.4 (0x00007fe611c2d000) libUtils.so.4 => /usr/lib/x86_64-linux-gnu/qtcreator/libexec/../libUtils.so.4 (0x00007fe61196d000) libclang-8.so.1 => /lib/x86_64-linux-gnu/libclang-8.so.1 (0x00007fe60ffc2000) <...further details omitted...> ``` Installing package "clang-8" completely resolved the issue. If that is not an available workaround, providing /usr/include/clang/8/include (symlink to other Clang include directory?) should be sufficient, but I haven't tested this.
